Arduino Nano with Helders LPF

Post by Robots86 » Tue Jan 22, 2019 2:42 am

Hello

Im working on a project which runs on a arduino nano. im running audio out of one of the pins. So its got some noise which I imagine is similar to that out of the GPIO pins on the Rpi. Would helders PWM audio filter help with this? Looking at the board there are 2 PWM pins. I presume this is just audio in?
Can anyone confirm if this is the case?

Each one is a separate channel but if you only have one just use one of the 2.

Don't contact me about obtaining my board files (as you will not get them). If my Boards or PCB Kits are sold out, they will be restocked as soon as I can get them and there is demand for them. You can join the mailing list on my Website to be notified when they are available.

Thanks Helder
Yeah I only need 1 channel. Im ordering the bare board from OSH Park. Im guessing I only need to populate half the board then?

Thanks again for the reply mate
